How To Choose a Window Company in Denver

With Denver's sheer size, you're sure to find a dependable window replacement company that matches your values and preferences. As you contact companies, keep the following factors in mind:

Window Cost by Type

When it comes to window replacement, value is most important. Each window you buy should deliver unparalleled durability at an affordable price point. Although premium windows may cost more upfront, they often yield better long-term value due to their extended lifespan. The style, material, and size of your new windows play the largest role in determining your final cost. Transom windows are inexpensive with their simple size and straightforward form factor, while a custom-cut arch window in a master suite will cost more. It's advisable to speak with a trusted window installer to determine your most suitable options.

This table shows average prices for various window types to give you an idea of what to expect.

Window TypesAverage Cost
Arched$225-$1385
Awning$326-$909
Bay$752-$5583
Custom$335-$930
Casement$260-$1509
Double-hung$121-$785
Egress$223-$557
Glass Block$44-$565
Picture$196-$1447
Single-hung$88-$1489
Skylight$111-$1344
Sliding$256-$1302
Storm$52-$368
Transom$272-$570

Window Material Cost

Materials also help determine a window's cost. You might pick a material based on your desired look, the local climate, and your energy efficiency goals. For example, wood windows can give your home an organic design without breaking the bank, but you'll have to invest more toward maintenance. Aluminum and composite windows cost more up-front, but they're incredibly durable against the elements, so you'll spend far less on maintenance.

Window TypesAverage Cost
Aluminum$52-$1489
Composite$537-$1207
Fiberglass$88-$752
Vinyl$181-$1675
Wood$268-$1509

Other Window Replacement Costs

Ask each contractor you're considering about labor costs, warranty fees, and permit fees. This will help you understand the total costs involved in the project.

Experience and Training

The longer a window provider has been operating, the better its workmanship will likely be. Speak with a company representative to learn more about its guarantees, public and private credentials, and experience. Company websites often have photo galleries showcasing previous work technicians have done.

Licensing and Credentials

Colorado's contractor licensing requirements are distinct compared to many states. There is no central board that licenses window companies, but they might still need licenses from local municipalities in which they operate. Colorado Springs and Denver license window installers, treating them as either general contractors or building contractors. For other areas, check with your local government.

Types of Windows Offered

The kind of window you prefer should factor into your company choice. Not every installer will necessarily be familiar with the window brand you want. A company website will show more about the styles of windows it specializes in, such as:

Equally important to your desired windows' shape is their framing. Ask your window company if it offers the frame material you want, such as wood, aluminum, composite, fiberglass, or vinyl.

Customer Feedback

Reading other customers' stories is a surefire way to screen window companies in your area. Trustworthy sources for customer reviews include Google, the BBB, and Trustpilot Referrals can also help you in your company search. Ask each company you're interested in for a list of references, and talk to family and friends about who they use for window installations.

Frequently Asked Questions About Window Replacement in Denver

What are the benefits of hiring a window installer?

By hiring a professional, you don't need to worry about making measurement mistakes or not having the right tools. A window installation team is well-equipped with the right supplies and knowledge to do the job safely and accurately. You can also get fast, informed answers to your questions and tailored guidance to make the most of your new windows

Are there tax incentives for installing energy-efficient windows?

Ultimately, the tax incentives you can claim are determined by the scope of your window replacement and the community you live in. You can claim up to 30% of the value of new efficient windows as a federal tax credit, up to $3,200 per year, until 2032. We also encourage you to contact your city or county government for more information on tax breaks specific to your area.

Do window companies have guarantees or warranties for their work?

Window companies often offer warranties for their services. Each typically covers problems with materials and workmanship for a specified period of time. It's essential to check the conditions of the warranty with a window company before signing a contract.
